Description

Technical Field

[0001] The utility model belongs to the field of motors and relates to a motor, in particular to a water-cooled motor. Background Art

[0002] In order to dissipate heat of the motor, a cooling fan is installed on the shaft or the motor is cooled by water.

[0003] However, existing water-cooled motors usually have a water-cooling casing on the motor outer cover, and the heat dissipation purpose is achieved by immersing the motor casing in water. However, the heat inside the motor is dissipated through heat exchange between the motor housing and cold water. This method results in low heat dissipation efficiency, and the motor assembled in this way is relatively bulky and inconvenient to move.

[0004] For example, the patent number CN2019212556651 is a sleeve-type water-cooled motor, which includes a motor and a motor cooling cover. The motor cooling cover is composed of an upper ring shell and a lower ring shell. The upper ring shell and the lower ring shell are welded together end to end. A liquid inlet pipe and a liquid outlet pipe are arranged on the surface of the upper ring shell. A barrier wall and a guide wall are formed inside the surface of the upper ring shell. The barrier wall is arranged between the liquid inlet pipe and the liquid outlet pipe.

[0005] The above patent arranges a motor cooling cover on the outer shell of the motor, which achieves heat dissipation by increasing the contact with the motor housing and using water cooling. However, this method increases the size of the motor in disguise, making it inconvenient to store. There is no surface fixing method for the cooling cover and the motor, making it difficult to ensure the cooling effect. Utility Model Content

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figures 1 to 8 As shown, the utility model can be implemented through the following embodiments: a water-cooled motor includes a shell 1, a stator 2, and a rotor 3. The inner wall of the shell 1 is provided with a guide groove 11, the outer surface of the stator 2 is provided with a U-shaped groove 21, a heat dissipation ridge 22 is formed between the U-shaped grooves 21, a U-shaped tube 8 is inserted between the guide groove 11 and the U-shaped groove 21, a water pipe 7 is installed between adjacent U-shaped tubes 8, a front end cover 4 and a rear end cover 5 are installed at both ends of the shell 1, a sealing ring 6 is installed between the front end cover 4 and the shell 1, and a water inlet conduit 61 and a water outlet conduit 62 are provided on the sealing ring 6.

[0025] A guide groove 11 and a U-shaped groove 21 are respectively provided on the inner wall of the shell 1 and the outer surface of the stator 2, and a U-shaped tube 8 is installed as a cooling pipe in the installation space formed by the guide groove 11 and the U-shaped groove 21, so that the cooling pipe fits the stator 2 as closely as possible and helps the stator 2 to dissipate heat; the U-shaped tubes 8 are connected by a water pipe 7, and the water pipe 7 and the U-shaped tube 8 are detachably connected, which is convenient for the processing, production and maintenance of the components; the sealing ring 6 is installed to isolate the contact surface between the U-shaped tube 8 and the water pipe 7 and the stator 2, ensuring that the coolant will not contact the stator 2 when it leaks, causing a short circuit in the motor; the water inlet conduit 61 and the water outlet conduit 62 are used to connect to an external cooling source; the front end cover 4 and the rear end cover 5 restrict the water pipe 7 and the U-shaped tube 8 to prevent the pipeline from moving and causing noise.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, an insertion portion 71 is provided at the end of the water delivery pipe 7, a limiting portion 72 is provided behind the insertion portion 71, a locking nut 73 is installed on the limiting portion 72, and the limiting portion 72 and the end of the U-shaped tube 8 are fixed by the locking nut 73.

[0027] The insertion portion 71 of the water pipe 7 extends into the U-shaped tube 8, receives the coolant from the U-shaped tube 8 and transports it to the adjacent U-shaped tube 8 to reduce the possibility of leakage. The limiting portion 72 is used to prevent the water pipe 7 from going too deep into the U-shaped tube 8; the locking nut securely connects the U-shaped tube 8 and the water pipe 7 to prevent the coolant from impacting the tube wall and causing the connection between the water pipe 7 and the U-shaped tube 8 to be disconnected, thereby strengthening the seal; the locking nut also has a limiting function to prevent the U-shaped tube 8 and the water pipe 7 from moving.

[0028] like Figure 5 As shown, a plurality of sealing rings 74 are embedded in the insertion portion 71. The plurality of sealing rings 74 enhance the sealing performance between the insertion portion 71 and the limiting portion 72, and can effectively prevent leakage from occurring at the contact surface between the insertion portion 71 and the U-shaped tube 8.

[0029] like Figure 7 and Figure 8 As shown, a T-shaped slider 221 is provided on the heat dissipation ridge 22, and a corresponding T-shaped slide groove 12 is provided between the guide grooves 11. The T-shaped slider 221 cooperates with the T-shaped groove to increase the contact area between the stator 2 and the housing 1, so that the heat of the stator 2 is transferred to the housing 1 more quickly, and the heat in the housing 1 is absorbed by the coolant in the U-shaped tube 8, thereby improving the heat dissipation efficiency.

[0030] like Figure 2 and Figure 4 As shown, a limit plate 81 is provided at the bottom of the U-shaped tube 8. The limit plate 81 and the rear end cover 5 cooperate to limit the U-shaped tube 8, prevent the U-shaped tube 8 from moving, reduce noise generation, and prevent leakage between the water pipe 7 and the U-shaped tube 8 caused by vibration.

[0031] like Figure 3 and Figure 6 As shown, a mounting hole 63 is provided in the sealing ring 6, and a sealing gasket 9 is provided between the mounting hole 63 and the U-shaped tube 8. The mounting hole 63 is used for the U-shaped tube 8 to pass through the sealing ring 6, and the sealing gasket 9 strengthens the seal between the U-shaped tube 8 and the mounting hole 63 to prevent the coolant from entering the interior of the housing 1 from the mounting hole 63 when leakage occurs.

[0032] The working principle of the utility model is as follows: after the housing 1, the stator 2 and the rotor 3 are assembled, the U-shaped tube 8 is inserted between the guide groove 11 and the U-shaped groove 21, and the rear end cover 5 is installed, then the sealing ring 6 is put on and the water pipe 7 is installed, the water pipe 7 and the U-shaped tube 8 are fixedly connected by the locking nut of the water pipe 7, and finally the front end cover 4 is installed, and water is passed through to cool the motor when the motor is running; if the motor needs to be disassembled or repaired, the above steps can be reversed.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0034] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
